Calcium Chloride catalyzed Intramolecular Oxa Michael addition of 2’-Hydroxychalcone to Flavanone
An efficient cyclization of 2’-hydroxychalcone to flavanone using calcium chloride as a catalyst was developed. The scope of the reaction was studied with substituted 2’-hydroxychalcone and these chalcones was converted into corresponding flavanone in good yield. The merits of this method are inexpensive and easily available catalyst, easy workup procedure, avoid use of toxic solvent

15 صفحه اولDiastereoselective synthesis of pitavastatin calcium via bismuth-catalyzed two-component hemiacetal/oxa-Michael addition reaction.
An efficient and concise asymmetric synthesis of pitavastatin calcium (1) starting from commercially available (S)-epichlorohydrin is described. A convergent C1 + C6 route allowed for the assembly of the pitavastatin C7 side chain via a Wittig reaction between phosphonium salt 2 and the enantiomerically pure C6-formyl side chain 3. The 1,3-syn-diol acetal motif in 3 was established with excelle...
متن کاملStereocontrolled synthesis of rosuvastatin calcium via iodine chloride-induced intramolecular cyclization.
A novel, stereoselective approach towards rosuvastatin calcium from the known (S)-homoallylic alcohol has been developed. The synthesis is highlighted by a regio- and stereocontrolled ICl-induced intramolecular cyclization of chiral homoallylic carbonate to deliver the C6-formyl statin side chain with a syn-1,3-diol moiety. An improved synthesis of the rosuvastatin pyrimidine core moiety is als...
متن کاملAddition of Alumina to Nanoporous Calcium Titanium Phosphate Glass-Ceramics and its Effects on Crystallization Behavior
Microporous Calcium Titanium Phosphate glass-ceramics have many uses in high-tech industries. For example, they have applications in catalysts industry. In this study, different molar percentages of alumina were added to a glass with P2O5 30, CaO 45, TiO2 25 (mol%) composition. The samples were melted at 1350°C and crystallization heat treatment was performed on...
